Classé amplifier and record your serial number for future reference a word about installation Every effort has been made to make the Classé Delta MONO simple and straightforward to install and use. It may be placed on a shelf, in a cabinet or on the floor near the speaker(s). As with all amplifiers, the Delta MONO generates some heat and care should be taken to allow adequate ventilation.
Unpacking and Placement unpacking your amplifier Carefully unpack your power amplifier according to the supplied instructions, and remove all accessories from the carton. Please take care when lifting the amplifier, as it is extremely heavy with weight somewhat concentrated near the front right corner.

Please note and record this number on the page entitled Important Safety Instructions for your future reference. operating voltage The operating voltage of your Delta MONO is indicated on the rear of the unit. Do NOT connect the amplifier to AC mains power of different line voltage.
Special Design Features highly refined This Classé amplifier utilizes our latest technology, implemented with the circuit design highest quality parts. A combination of careful part selection and circuit layout combined with an extended class A operating area enables superior performance under all conditions.
Front Panel Standby/ON Button & Status Indicator LED The front panel Standby button will toggle the amplifier between operate, its fully operational state, and a standby mode. (See also Wake on Network). The current state of the amplifier is indicated by the LED status indicator in the Standby button.

Caution! If you see the Standby LED indicator blinking red, please check that all external connections are cleanly made and secure. If no fault is immediately obvious, try to reset the amplifier by pressing and holding the standby button. If the unit does not reset or continues to enter protection mode, please call your authorized Classé...
Signal-to-Noise ratio by 6 dB; they also do an excellent job of rejecting noise and interference that might otherwise be picked up between the components. If executed as in the Delta MONO with a high degree of symmetry between the inverting and non-inverting signal paths, balanced connections can offer the best performance.

Installation Your new Classé amplifier is quite simple to set up and enjoy. Please follow the steps outlined below in order to safely set up and use your new amplifier. Important: It is always a good idea to power up your power amplifier(s) last, after everything else has been powered up and has stabilized.

The Delta MONO utilizes premium quality binding posts that provide an optimum torque feature which ensures the correct pressure or tightness of the connection while preventing damage that can result from over- tightening. Secure the speaker cables by tightening the binding posts until you hear the clicks indicating you’ve reached the proper torque for the...

Classé customer support. The Delta MONO Event Log can report the following events interpreted as follows: • DC Output — DC from the source has exceeded the amplifier’s ability to correct for it.
Care and Maintenance To remove dust from the cabinet of your amplifier, use a feather duster or a lint-free soft cloth. To remove dirt and fingerprints, we recommend using a microfibre cloth and static free lens cleaner such as you would use for cleaning a flat panel display.
Troubleshooting In general, you should refer any service problems to your Classé dealer. Before contacting your dealer, however, check to see if the problem is listed here. No sound, and Standby LED is not lit. • The amplifier is not plugged into the AC mains, or the AC mains are down (circuit breaker, fuse).

The AC mains fuse is blown. There is a specific troubleshooting procedure for a blown AC mains fuse, since this rare occurrence sometimes indicates a significant problem. Please use the following steps, in order: a. Disconnect your amplifier from the AC mains, as well as from its input connections and speaker connections, and remove the fuse cover on the rear of the unit.
